Getting Started
Follow this order for the smoothest setup:
That's it — reminders will fire automatically on schedule from there.
SMS reminders require the customer to have given explicit consent first. If the SMS channel options are greyed out, it means the selected customer either has no phone number on file, or hasn't had SMS consent recorded.
To fix it:
Both names appear directly in the reminder messages. For example:
"Invoice #1042 from Acme Plumbing is due in 3 days - $850.00. Already paid? Contact Acme Plumbing. Reply STOP to opt out."
Make sure your business name in Settings and your customer names are spelled and capitalised exactly how you want them to appear.
Reminders
Reminders are processed once daily, automatically. The default schedule sends reminders at these intervals relative to the invoice due date:
You can customise which steps are enabled per invoice by expanding the Reminder Schedule section when creating or editing an invoice.
No problem. Open the invoice and tap Send Reminder Now. You'll get a choice:
Open the invoice and tap Mark as Paid. This immediately stops all future reminders for that invoice.
Customers can also click the link in their reminder to mark it paid themselves — this has the same effect.
Yes. Open the invoice detail and tap Send Reminder Now. This sends the most recent due/overdue reminder immediately, bypassing the daily schedule.
The button only appears if there are unsent reminders available to send.
SMS & Email
Example for a 3-day overdue invoice:
"Invoice #1042 from Acme Plumbing is 3 days OVERDUE - $850.00. Contact Acme Plumbing to arrange payment. Already paid? Mark it: [link]. Reply STOP to opt out."
All SMS messages include a STOP opt-out link and your business name.
Yes — go to Settings → Reminder Messages. You can set custom subject lines and body text for each reminder step, for both email and SMS.
Use merge fields to personalise each message: {{customer_name}}, {{invoice_number}}, {{amount}}, {{due_date}}, {{business_name}}, {{reminder_context}}.
If no custom template is set, a sensible default is used automatically.
Twilio automatically handles STOP replies — that customer's number is unsubscribed and will not receive any further SMS messages from your account. This is handled at the carrier level and cannot be bypassed.
Customers can re-subscribe by replying START.
